You got this backwards. In GR, changes in gravity propagate at the local 
symmetry speed, given by SPECIAL Relativity. It "just so happens" [#] 
that electromagnetic waves travel at this same speed in vacuum. It is 
merely an historical anomaly that it is called "the speed of light", due 
to the round-about way Einstein first described relativity in 1905 -- 
the spacetime symmetry is MUCH more fundamental and important.

	[#] This is neither happenstance nor accident....

BTW modern derivations of SR don't use electromagnetism at all.

Nope. YOU have imposed specific units onto the formula/equation. The 
equation itself does not impose any particular units on its variables 
and constants [@], it merely requires that they be self-consistent.

	[@] There are many systems of units in common use. You
	seem to think there is only one.

Making stuff up and pretending it is true is USELESS. Grow up!
